For Stereo you may want to use an interlaced mode. This assumes that each eye want a 1280x512 picture, so is actually only as fast as a 1280x1024@60Hz non-interlaced mode. Note that some drivers/cards don't support interlaced modes (my i815 for instance). If I've correctly translated the output from the GTF spreadsheet, this is the nearest to a standard 1280x1024 mode with 60Hz frames/120Hz fields: Modeline "GTF1280x1024_120i" 112.889 1280 1496 1632 1712 1024 1090 1096 1099 Interlace -HSync +Vsync It is a whisker too fast for my monitor so I haven't tested it properly, but it does appear to do what it is supposed to. -- Dr. Andrew C.
